Time Pressure is a very specialized strategy which involves contacting the ball almost right off the bounce such that the ball is returned to the opponent before he is ready to hit again.  The shots used have characteristics of both controlling and attacking shots.  The ball speed is more in the control range, but the commitment to play every shot from the more difficult off the bounce location with the intention of winning with that shot is more attacking in nature.  Overall, using Time Pressure requires more of an attacking (rather than controlling) mindset.  Contacting balls over the table rather than letting them come off the end of the table is a hallmark of the Time Pressure strategy.

Because the shots are played off the bounce,  Time Pressure is a close distance only strategy.  It is also not very effective unless the opponent is also playing close distance.  Blocking is the primary stroke used although very close to table counterhitting can be used.  In both cases borrowing power from the opponent's shot is important since off the bounce strokes are inherently more compact and do not generate as much power on their own.

The key to using the Time Pressure strategy is the ability to play the ball right off the bounce and even contact it over the table if the ball is a little short.  Besides the obvious reduced time to react, Time Pressure play has two other effects.  There is a kind of Timing Disruption effect since normally balls are allowed to come off the table before being hit.  Opponents are often not even preparing for the balls return at the time it is hit.  Taking the ball over the table also negates the effects of widely angled balls since they never get the chance to continue going wide outside the table.  Thus it is generally better to attack the Time Pressure player deep to the corner or middle than short and wide.  When played as a synergistic strategy to Pattern play, there are fewer balls played over the table than in a pure Time Pressure strategy.  In the mixed strategy the Time Pressure comes from playing the ball very close to the end of the table rather than the more normally expected one step back position.

Because the Time Pressure player needs to borrow power, they generally do not attack first.  Using Early Power and attacking on 3rd or 4th ball can be an effective complimentary strategy to Time Pressure especially if the opponent tries to deal with the reduced time by taking some power off their serve return or their 3rd ball.

Pattern and Time Pressure are natural synergistic strategies.  If Time Pressure is the more dominant then there are more shots played over the table and the ball movement pattern tends to be repeated shots to one location followed by a surprise location change.  If Pattern is more dominant there is more shot to shot ball movement and the ball is more often played near the end of the table.  Time Pressure strategy can turn into an Attrition plus Time Pressure strategy if both players are good at dealing with each others shots.

The Early Power player using 4th and 5th ball kills after topspin shots is vulnerable to Time Pressure since the topspin setup shot (2nd or 3rd ball) can be returned very quickly.  Using an underspin 2nd ball or 3rd ball as the setup can negate lots of the time pressure on your attacking shot.  And using 2nd or 3rd ball kills gets your attack in before  Time Pressure can be applied.  The Pattern player is probably the most vulnerable to Time Pressure.  In addition to having less time in which to execute precise placements, the over the table blocks negate the effects of their wide placements (their primary finishing shot).  The compact strokes ( mostly blocks) of the Time Pressure player are also less vulnerable to the transition pressure of the Pattern strategy.  To win the Pattern player has to find a pattern that the particular Time Pressure player finds difficult to deal with.  Since the Time Pressure player is not attacking with power, sometimes a non standard pattern going into the Fh power zone will work.  Attrition or Late Power from mid or far distance force the Time Pressure player to play a different strategy.  A close distance Late Power strategy based on pushing and then pick hitting can be effective if the Time Pressure player can not open strongly.  Of course if the Time Pressure player is using topspin serves, this would only work when the Late Power player was serving unless he is able to use a chop serve return.

The ability to play returns right off the bounce ( even playing shorter balls over the table) is the key factor in making the Time Pressure strategy work.  To do so you need compact strokes and good in/out footwork to get in over the table on short balls and still get back for deep attacks.  As such the Time Pressure player needs to practice against strong deep attacks and needs to use drills with different length returns to practice this in/out play.  When playing players who can effectively retreat to mid and far distance, the Time Pressure player needs another strategy.  Since they normally would have good blocks, they can develop a close distance Late Power strategy using deep blocks to control their opponent, short blocks to bring them in closer, and a punch block or fast counterhit as a finisher once they are in closer behind a weak return.  

Time Pressure is a specialized, close distance strategy, used against other close distance players, particularly Early Power and Pattern Players.  The Time Pressure player needs to develop an alternative strategy for dealing with mid and far distance players since Time Pressure is not very effectice against those players.  Close distance Late Power based on control blocking is the closest fit to what they do in the Time Pressure strategy.

The Pattern strategy works best for close distance players since moving away from the table reduces the angle of attacks and gives your opponent more time for stroke recovery and Fh/Bh transitions.  It can work from mid distance for aggressive 2 wing loopers who can be consistent with enough power to put some pressure on the opponent's footwork and transitions.  

Placement is the critical feature of the Pattern strategy.  The Pattern player needs the ability to hit precisely to many different locations against a variety of incoming shot types.  The ability to disguise where the shot is going to be hit is very useful for pattern players.  Many pattern players use a Bh punch block stroke whose direction is very difficult to recognize until the ball is hit.  The Pattern player needs to practice multiple placements against both topspin and underspin and needs to practice specific patterns they expect to use.

Pattern players can use any type of shots except chops and lobs.  Aggressive long pushes are very important because they allow the Pattern player to both move his opponent slightly out of position early and start his pattern early in the point.  Mid distance Pattern players usually do not use blocks because they are too slow to create footwork and transition problems.  Pattern play from mid distance with blocks usually develops into Late Power play with Pattern play as a synergistic strategy.

There is not a complementary strategy for the Pattern strategy.  However, just as in the case of Late Power, some players play a hybrid Early Power/Pattern Strategy.   They look for very specific reurns that they can 3rd or 4th ball kill, but if those do not come they go right into their pattern.  The serves and returns used may not be the typical Early Power serves since they must function both as setting up an attack as well as setting up the pattern.

There are synergistic strategies for use with Pattern play.  Time Pressure combines well with Pattern's ball movement to put high demands on the opponent's footwork and transitions.  Timing Disruption, particularly the use of a slow short block, can be an effective addition to the Pattern game.  Pattern play blockers can add Spin Variation to the overall strategy to get even more errors from opponents.

The Early Power strategy is the best natual strategy against Pattern play since it tends to end the point before the pattern can develop enough to cause problems.  However, since it is played close to the table, the Early Power, player is more vulnerable to the footwork and transition pressure than a strategy played from mid to far distance.  Pattern versus Pattern is often seen in the women's game.  It is often combined with Time Pressure.  In that case it simply comes down to who picks the better patterns to play and who can execute those chosen patterns.  Late Power from close distance is vulnerable since it allows the pattern to be developed against relatively light pressure.  Late Power from mid distance can be very effective since the playing distance reduces time pressure on footwork and transitions.  The Pattern player can make the mid distance player use a lot of energy covering the return angles they can generate.  But control loops from mid distance are usually more dificult for the close distance Pattern player to deal with so the Pattern player is often forced to use less aggressive angles or move slightly back which reduces his angles and effective pressure on transitions.  Both Late Power and Attrition played from mid distance with heavy topsin can be effective against the Pattern Player.  Time Pressure can break down the Pattern players ability to execute their patterns.  Pattern players who use larger loop strokes are more vulnerable than those using compact shots such as blocks and counters.  Timing Disruption srategies which slow down play can reduce the effectiveness of Pattern play.  However, slower, shorter balls do allow some Pattern players to execute extreme angles so this kind of Timing Disruption's effectiveness is highly dependent on the skill set of the particular Pattern player.  Any strategy played from far distance negates a lot of the Pattern strategies effects.  However, since the Pattern player is good at placement,  any far distance player will need extra stamina to repeatedly cover the angled shots the Pattern player is good at generating.

As a Pattern player, placement is the key against any strategy.  One key feature is the ability to play very wide angles.  This requires using a slight reduction in speed in order to get the ball to land in the shorter distance available on very wide angles.  Practice on mixing shots to the short wide angle with shots deep to the corner and elbow is essential.  Against Early Power players hitting the elbow early is very important.  Against any strategy played from distance, the Pattern player needs to both move the opponent wide side to side and sometimes make them move in and to the side at the same time.

In summary, Pattern play is an effective strategy for close distance players and is especially good against other close distance players.  It does not work nearly as well against mid to far distance players and is vulnerable against heavy topsin played from mid distance by a control looper.
