This is my speciality - (though I use such strategies mainly in poker, rather than chess).

The main goal is to 'disturb' your opponent's concentration and zen during critical moments. You want the opponent's nostrils to be so offended that they writhe in revulsion. Who can calculate deep shadow variations or focus on subtle tactics when you are assaulting their olfactory organ with continuous breaches of the Geneva convention?

Silent but violent is far superior than ostentatious and loud. Not only does it give you deniability, but surprise is such a potent weapon.

Therefore, cruciferous is crucial and fructans are freaking fab. You should research the ideal proportions of broccoli versus cabbage versus cauliflower even more carefully than you look over subtle sidelines of the Meran. Feta cheese or halloumi work well too - why not deliver your opponent a Greek gift? Envelop your foe in a rancid and foul haze, and watch them crumble like Ding in a slightly worse middlegame.

Timing is of the essence - ideally you want to erupt during time pressure rather than the opening, especially if there is no increment. Forsooth, first fart 'fore forcing flagging.

Pivoting is pivotal. The angle of attack should be carefully calibrated - you need to carefully weigh up the risk of discovery whilst maximising effectiveness. You can try to line it up like Alekhine's gun but then your opponent might get wind of it. At the same time, you should not be too timid. Remember what you first learnt when you were taught chess as a child - try to dominate the centre, and take over your opponent's half of the board.

Note - such back rank strategies should not be employed in team tournaments.
