Titled Tuesday or Tactics Tuesday ?

Another episode of Titled Tuesday this week !

The winner ? the chess.com player @Jospem  aka Jose Martinez from Peru 

https://www.chess.com/tournament/live/titled-tuesday-blitz-december-14-2021-2793478

But Titled Tuesday can also become Tilted Tuesday ( going on Tilt is easy in such a strong field).

But this Tuesday was Tactics Tuesday !

Example 1 (warm-up): @Jospem the winner , who is only 22 years old !

How did the Jose Martinez with Black get a decisive advantage here ?

Black to play

Black was able to spot a fork using the knight. Tactics in time scrambles ! 

By the way, who is looking forward the World Blitz ( and Rapid) in Poland later on this month ?  Magnus Carlsen, but also Hikaru Nakamura, Vidit,Caruana and probably Artemiev,Firouzja,Grischuk,Dubov,Duda  should be there.... maybe Wesley So, Jeffery Xiong, Andrew Tang will travel there too. Not sure about @DanielNaroditksy who may comment on the action.

Example 2 : a nice example by Jeffery Xiong. If you don't know this super strong american player, check out an earlier Titled Tuesday Tale here https://www.chess.com/blog/thechesscorner64/titled-tuesday-tales-2

White to play and win 

Example 3: Jeffery Xiong again. He finished 2nd this time and 1st last week. A strong contender for a medal in the World Rapid & Blitz Championship for sure !

Black was able to find a hidden tactical motif here.

Black to play !

For some reason, I cannot annotate the moves with ! or ? within the diagrams. Probably something chess.com will fix (it happens from time to time)

Last example #4 GM Pichot from Argentina defeating GM Bacrot from France

White to play and win !
