T57- T59 Summary

As a matter of completion, here's a summary of Openings played in the last three TLs, since I seem not to have done this individually, plus a couple of short checkmates !

For me, T57 was the longest with 9 games played, as Magnum Ignotum reached the final. ( In fact we have reached the play-offs in 5 of the last 6 seasons : not bad !).

Although I had good results in T57, this was the tournament where I changed my repertoire for both Black and White., adopting e6 as my main defence and also moving to 1.d4 as White.

These proved to be consistent with main TL openings, as e4 is still the most played, and the Sicilian, French, and Caro-Kann the top replies. No change there.

For White, the main change, compared to T56. appear to be the increase in the the use of general Queen's Pawn openings, ie systems such as the London or Colle, as well as non-Queen Gambit openings, such as the Trompowsky.

Nice to see the short mate rearing it's head again...

Another quick mate in the Caro-Kann

Yes, its that damned Caro-kann !  Black really needs to be careful !

This short game started with 1.f4, but transposed to a King's Gambit, leading to mate in 9.

Longest games ?  Again, over 100 moves there were 9 games, only 4 of which were draws, including the longest at 124 moves.

Finally, as a minor exercise, work out the short mating sequence here, where Black resigned after 8 moves, after a failed Latvian Gambit !
