This was another Australia Day Tournament game where I played reasonably well with some interesting features in the match. Firstly, it was another game of the standard (Falkbeer) Vienna Gambit, but where my opponent declined with d6. Although this is suboptimal compared to the best response, d5, it is not bad and isn’t immediately winning for White.

A few moves later, the game transposed into one of the lines of the Lion Defense, which is apparently a reasonably good defensive system for Black. I wasn’t aware of the Lion Defense until I explored this in the analysis. One of the features of the Lion Defense is that it is a defensive system and can be used against a number of White openings, especially against e5. The Lion Defense doesn’t immediately challenge White for the centre, and thus, can avoid some of the lines in the Italian and Ruy Lopez, which might take an e4 player off guard. It is considered flexible as it can be entered into from several openings, for instance, the Pirc Defense and the Philidor Defense, and can also transpose afterwards into some other systems.

It’s considered perhaps not as robust at higher level play, but from some of the commentary I’ve read, many people consider it a fine system to learn as an alternative to something like the Sicilian Defense. However, it does have some system disadvantages, especially for a player who perhaps is not familiar with using the Lion, which I suspect might have been the case for my opponent in this game.

Firstly, the relatively more passive and waiting nature of the defensive system can potentially result in Black being overwhelmed with just a very aggressive attack by White. My understanding is that one of the ideas of the Lion is that Black lies quiet, well defended, waiting for the right opportunity to strike out. However, with their space being a bit cramped, development, especially of the bishops, is delayed and potentially impaired. This was certainly the case in this game, where my opponent ended up unable to develop, or effectively develop, both bishops, both rooks, and one knight.

Secondly a delay in castling resulted in an opportune attack on my opponent’s king while still in the centre, resulting in a loss in the right to castle. This ultimately proved devastating as with the centre opened in the middle game, my superior development resulted in an overwhelming advantage of +6 by move 12, and a forced checkmate line by move 17.
